Top Leapers / Utg AR 15 lower parts? By the year 1959, the Armalite Company was in the middle of some extreme financial problems, and were unable to manufacture or experiment more with their new rifle. To combat this, they ultimately sold off the design of the AR 15 to another gun manufacturer, Colt. Colt would later go on to become one of the biggest producers of the AR 15 platform for a great length of time. Around that same time, gun manufacturer Remington Arms was in the process of developing a new, small diameter cartridge with increased velocity, specifically for use as a medium-range rifle caliber. This .223 cartridge was then used as the basis of Stoner’s designed scaled-down AR 10 that he was experimenting with. This later went on to be named the Armalite Rifle 15, or AR 15 as we commonly know it as today.
The name M-LOK stands for modular lock, and was created by Magpul, a large name in the industry. This innovative new way to mount accessories, unlike keymod, isn’t an open source system. While any company or manufacturer is free to license it if they ask permission, but the M-LOK system must be made with the same quality as the original design. This means you are practically guaranteed that any M-LOK mounting or accessory attachments are all going to be very well made and uniform. Instead of the keyhole shaped holes that keymod uses, M-LOK uses narrow slits and T-shaped nuts that lock into place once they are installed. This system has many advantages, including the fact that accessories can be mounted either towards the front or rear of the slit you are using, giving you the ability to put it in just the right spot. This system also works well with polymer handguards.
A common misconception about cold hammer forging is the “cold” part of the process. These barrels are usually done at room temperature. The pressure that is then generated creating these barrels does heat them up a bit, and the barrels must also be stress-relieved by further heating after forging. While this whole process can be done by heating up the barrels to extreme temperatures, today’s technology does not require it and is why it is called “cold” hammer forging.

Many polymer drop-in handguards will be made of two different pieces that will fit around the barrel. They are generally fastened together by a handguard cap towards the front, and secured by a delta ring assembly in the rear. They get their name from how easy it is to install them, or to “drop-in” a new one. Installing them is super easy, and can literally be done in less than a minute. Simply pull back on the spring loaded delta ring to remove the current handguard, follow the instructions on the new one and put it in almost in reverse of removing one and there you go! Brand new handguard in no time! Most drop-in polymer handguards are offered in different lengths, in order to accommodate the varying gas system lengths of whatever AR-15 they are going on. They are generally the cheapest option, but they do have one slight disadvantage. Because of their design, they incorporate a handguard cap that is usually in contact with the forward portion of the barrel. This can possibly affect accuracy, especially if using fore grips or bipods with the handguard. This is not always the case, but something to be aware of if precision accuracy concerns you.
